Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a perspective view of an aquatic plant recovery ship embodying the present invention . The aquatic plant recovery ship comprises a cutter ship A and a collector B.

The hull 10 of the cutter ship A is of a catamaran type having a passage 12 for collecting water plants between a pair of left and right floating bodies 11a and 11b. Two floating bodies 11a and 11b
Is connected to the bridge (not shown) on the width direction, it is integrated. The inlet 14 of the passage 12 is opened in a funnel shape so that a water plant having the same width as the hull 10 can be guided into the passage 12.

Between the bows of the floating bodies 11a and 11b, there is installed a rotary cutter 15 having the functions of cutting, cutting and sending back water plants. The cut by the rotary cutter 15, morselized been aquatic plants, the passage 12
Landed by the unloading conveyor 60 installed inside
After that, it is housed in a collector B which is connected to a rear portion of the cutter ship A by a connecting rope 16.

The rotary cutter 15 is a blade 17 for cutting, cutting and post-feeding aquatic plants, and the blade 17 concerned.
A shaft 18 for fixing the shaft , and a drive unit 1 for giving rotation to the shaft 18.
It is composed of nine. Communicating the rotary shaft 18 and the driving unit 19
For the connection , an endless rubber belt 20 or a chain belt may be used as an intermediate medium, or a shaft direct connection drive system may be used.

The rotating shaft 18 to which the blade 17 is fixed is adapted to rotate in the same direction as the traveling direction of the hull 10.
It The rotation direction of the rotary shaft 18 is the same as the traveling direction of the hull 10.
By the direction, the rotary cutter 15, pruning so as to involve the water plants floating flourish waters end in the direction forward of the hull 10, cut, and can be sent backward.

[0014] In FIG 1, the rotary cutter 15
The left and right floating bodies 11a and 11b are integrally formed, but as shown in FIG. 2, the left and right independent rotary cutters 15 , that is, the separate rotors
The leaf cutter 15 may be used .

The blade 17 is not an upright type, but is shown in FIG.
As shown, from the blade edge 17a to the blade edge 17b, sickle neck
It has a curved shape. In this way the blade 17
By having a moderate bend, in addition to the above functions, aquatic plants
Can prevent the blade 17 and the rotary shaft 18 from being entangled with each other.

I.

Further, the number of the blades 17 is determined by the length of the rotary shaft 18 of the rotary cutter 15 (width of the hull 10) and the type of aquatic plants to be collected.

The blade 17 may be fixed to the rotary shaft 18 , but in order to facilitate maintenance and replacement of the blade 17, the socket 2 having a bolt hole 21a in the rotary shaft 18 is used.
3 is fixed and the socket 23 has a similar bolt hole 21b.
It is convenient to use a so-called connection type in which a blade 17 having a blade is inserted and both are connected by a bolt nut (not shown).

As shown in FIG . 3, the blade 17 rotates
The shaft 18 is mounted so as to be oriented in the axial direction of the rotary shaft 18.
It is worn. Furthermore, as shown by the broken line in FIG.
Only the tip portion 17d of the blade 17 is laterally attached to the blade 17.
By bending it in a hook shape in the direction,
Go up.

[0020] Installing to the rotation axis 18 of the blade 17 may be a blade 17 attach one for one cross-section of the rotary shaft 18, but if a more strips of the one transverse
You can attach two or three to the surface . Note that the mounting positions of the blades should not overlap in one cross section .
And is arranged around the rotary shaft 18 at a predetermined interval.
Is desirable.

Further , the portions near both ends of the rotary shaft 18 are
Increase the implant density of the blades 17. This is to make the cutting and separation of the collected water plants and the water plants that escape to the rear of the hull 10 more effective.

The above-mentioned unloading conveyor 60 uses a mesh belt 61 as shown in FIGS . 6 and 7. For mesh belt 61 itself, which does not interfere with the flow of water, aquatic plants
Can be easily collected. Furthermore, on the mesh belt 61
Is provided with a catcher fin 62 having a Y-shaped tip for hooking water plants . The catcher fin 62 has a rod-like shape so that it does not push the water forward when it is in water. By using the Y-shaped catcher fins 62 (bars may have various shapes), it is possible to reliably place water plants on the unloading conveyor 60 without being affected by the rotation speed of the belt.

The drive source 64 of the unloading conveyor 60 may be of a direct coupling type with the rotary shaft 63, or the rotary shaft 63 and the drive shaft 64 may be connected with an intermediate medium such as a rubber belt or a chain belt.

As shown in FIG. 5, in addition to the rotary cutter 15 (referred to as front rotary cutter),
A rotary cutter 15a (referred to as a rear rotary cutter) having the same specifications as the front rotary cutter 15 in the passage 12 behind the front rotary cutter 15.
May be equipped . Cutting, cutting, and feeding the aquatic plants backwards
The front rotary cutter 15 alone can exert its ability, but by arranging the rotary cutters 15 and 15a in two stages in the front and rear, it is possible to make water plants into pieces and to feed them backward more smoothly. , That ability can be fully demonstrated.

In the case of a double rotary cutter type aquatic plant recovery boat equipped with a rear rotary cutter 15a in addition to the front rotary cutter 15 , the unloading conveyor 60 is not directly behind the front rotary cutter 15 but the rear rotary cutter 15a. Placed immediately after.

The cutter ship A has a propulsion unit 25 driven by the engine 25a to allow self propulsion.
On both sides of the propulsion unit 25, floating to water plants, timber,
To prevent the inflow of floating materials such as vinyl , a protective net 26
Is attached.

The rotary cutters 15 and 15a, the unloading conveyor 60, and the propulsion device 25 may be operated by operating them remotely from a control console 27 provided on the floating body 11a.

The drive sources for the front rotary cutter 15, the rear rotary cutter 15a and the unloading conveyor 60 are:
They may be shared, but they may be independent.

The above-mentioned collector B may be of any shape as long as it can store the collected waterweed, but it is convenient for dehydration treatment and unloading of water hyacinth that 95% of the total weight is water. Considering this, the stilt type catamaran type collector 30 is preferable.

As shown in FIG. 8, the raised floor catamaran type collector 30 includes a mesh type floor 31 for drainage,
The floor 31 is provided with a collecting portion 33 composed of a mesh type wall 32 stretched around the upper part of the periphery.

Even if aquatic plants are piled up directly on the collecting section 33,
It is good, but the net 34 is arranged in the recovery unit 33, and water plants are piled up on it. Then , the water plants are hoisted together with the net 34 by a crane or the like, and are unloaded as they are on a land or a transportation medium such as a truck. Mesh floor 31
Are supported by the floating bodies 35 arranged on the left and right. The upper surface 36 of the floating body may be used as a part of the mesh floor 31, but a pillar 37 may be provided between the mesh floor 31 and the floating body 35.
If the mesh type floor 31 and the floating body are integrated through the columns 37, the water can be drained more effectively.

The raised-floor catamaran type collector 30 is connected to the cutter ship A by a connecting rope 16 and towed.
The loading and unloading of water plants on the collecting unit 33 is continuously performed by the mesh-type unloading conveyor 60 provided on the cutter ship A.

This invention is a buoy type such as water hyacinth
Water plants float even form a single or flock, and or cut into small pieces by the addition of artificial damage, be one obtained by utilizing the property that float also be compressed, pulling moderately cut weeds After changing to an easy form, it can be pulled up from the water surface and collected in the collection section.

[0034] The lower portion of the rotary cutter 15 described above have been submerged, the blade 17 is rotated backward under water, rotated forwardly on the water surface. As a result, the rotation of the rotary cutter 15 causes a water flow, and the blade 17
The aquatic plants that have been pruned and cut by the above are continuously transferred rearward by riding on this water flow. Since the waterweed thus cut flows backward along the hull 10 without staying in the bow portion, the recovery boat can operate without being hindered by the waterweed even in the aquatic plant water area.

Further, the water flow generated by the rotation of the rotary cutter 15 also acts as the propulsive force of the recovery ship. Further, the raking of the water plants and the discharge to the rear thereof act as a propulsive force for the recovery ship, because the blades 17 perform the action of traveling in the water plants like crawler .

[0036]

As described above, according to the present invention, the bow portion of the hull is
The cutter installed on the rotary shaft and the entire blade are shaped like a sickle neck.
With a plurality of blades that are curved and the tip is bent like a hook
And each blade except the blade tip
Since most of them are attached to the rotary shaft so as to be oriented in the axial direction of the rotary shaft, it is possible to efficiently perform cutting, cutting and post-feeding of a buoyancy type water plant that floats on the water surface like water hyacinth. . Furthermore, since the water flow generated by the rotation of the blades can be effectively used as the propulsive force of the aquatic plant recovery ship, it is possible to perform efficient work without waste.
